This paper points out that there are three key technologies to solve the current intelligent parking problem:the first is how to achieve high-precision parking location positioning;the second is how to accurately detect the idle status of parking spaces;the third is to build an interconnected parking information network system and connect it to the cloud platform,achieving big data sharing of parking information throughout the city.Therefore,this paper designs an intelligent parking system based on OneNET cloud platform and Beidou GPS dual-mode positioning,which can theoretically solve the above three key problems.The system has been tested and operated normally,with normal data transmission and reception.The positioning data of each sensor and Beidou GPS is accurate,and the cloud platform data update is maintained between 1～2 s.Prove that the smart parking system has accurate monitoring of parking space status,precise positioning to the decimeter level,and fast and timely data uploading to the cloud platform for storage and display.It can improve the utilization rate and turnover rate of the parking lot and facilitate the travel and life of car owners.
